To all whom it ma concern:

Be it known t at I, GUsiAvic P. Minnwaiin'r, a citizen of the United States, residat Winona in the county of Winona.

,-6 and State of Minnesota, have invented certain new and useful Im rovements in YehicleSpring Jacks, of w ich the following is a spec'iiication.

'My 'nvention relates to an emergencyagr repairing jack for the laminated bc r springs of automobiles or other vehicles.

The main object is to provide a novel, simple, elcient and durable article to accomplish the purpose stated and at the same time one of such a construction that it may be interposed intermediate the spring and side beam of a chais of an automobile; one anchor plates with 'stubs to extend interiorl; of the spring -to enable mounting of t sprin a er anchoring of the anchor plates; one aving anchor means engaging the spring and capable of adjust- A ment to facilitate attachment to different widths of springs; one having abutment lgs to engage a side beam of a chassis, depending lugs, and hook bolts capable of enagement with the said side beam and bemounted by and fastened to the depend its the above and other objects such as will hereinafter appear, in View, t e invention has been embodied in one preferred form as hereinafter described and illustrated in accompanying drawings, whereg5 mij 1.

l4 igure 1 is a view illustrating my inven tion in side elevation and inconnection with fr ents of an automobile bolsterspriiig `side beam 'of an automebile chassis; g. '2 is an end view of 'my improvements in connection with thefragments of Fi 1 which are shown in cross section, and ig. 3 is a plan view of one of the anchor plates to the bolster spring. gRefe'rrilig1-specifically to tie drawings, 1 idesignatest e upper section or top of au elliptic automobileor other vehiclebolster ring ooniposed'of a plurality of laminated eaves 2, as usual. Disposed over the sprin 1 and spaced therefrom, is the usual side earn 3 ofthe automobile chassis. As is well known, one or more of the leaves 2 often break in practice, 'resulting in the weakening and reduction of eliieiency It is `with a view to strengthening the s ring or repairing it under the last mentiope con' of the bolster spring.l

dition, that the present invention has been devised.

Essentially my improvements comprise a compression spring 3, an anchor device 4 and an anchor device 5. Spring 3 may be of 'any referred construction and tension, but pre erably is enlarged intermediate its ends as shown to minimize the chances of y buckling.

The device 4 may comprise a plate 6 adapted to engage the under surface of beam 3 and have one or more lugs 7, integral therewith, to overlap the beam. Also said plate 6 preferably has a plurality of downwardly extending lugs 8 which mount bolts 9 having hooks 10 to overlap the lower flange of beam 3 and adapted to be fastened through the medium of nuts 11 ridable on screw threads of the bolt.

As to device 5, it may comprise anchor plates 12 and 13 to respectively engage lthe upper and lower faces of spring sectionv 1 and to preferably overlap the spring leaves 2 where broken, as suggested. at 14:. Plates 12 and 13 have laterally extending leaves 15 each of which is providedwith a trans versely elongated slot 16. .Slots 16 of plates 12 and 13 are adapted to register and receive fastening bolts l which, by means of nuts 18, are clamped to the spring, section 1. Due to the elongation of slots 16, the plates 12 and 13 may be fastened to spring sr ctions of different Widths. A

Extending from the plates 6 and 12, toward each other, intermediate the spring section 1 and beam 3, are studs or thimbles 19, integral with the respective plates and being preferably hollow so as to be of minimum weight.

In use, should one or more of the leaves of a spring section like that represented atl break, plates 12 and 13 may be brought in overlapping relation with respect to the break and then clamped in place by the bolts 17. Thereafter, late 6 s secured to the beam 3 with lugs ab'ilttin the beam on one side and the hooks 10- a gin .it on the other and beingfastenedby t e nuts 11. The thimbles 19 are in aliement and after compressing the spring 3, it may be positioned and iermitted to eX and so as to surround t-ne t imbles. This prin preferably tensioiied to a consider ble agree so as .111)V to absorb shocks. y y

Primarily the invention s ves as a repair device for a broken or weal ned'laminated s he understood that changes in the spring and body of a vehicle,

ugs integral ond mentioned lugs,

spring structure. However, at the same time, it Serves as a bolster for the chassis.

Since merely the preferred embodiment has been illustrated and described itis to details o! construction may be resorted to Within the spirit and scope of the appended claims. I claim: l 1 l. In combination with a supporting s ring inter osed therebetween, an anchor p ate for sai spring, a lug on said plate to overla one of said members, a second lug on sai plate, a-hook bolt engaging the last l5 mentioned mem r, being mounted in the second mentioned lug.

2. In combination with a' supporting spring and a body of a vehicle, an anchor late associated with one of said members,

the last mentioned member, integral lu on said plate extending in the opposite dyieiection to said lugs, hook bolts engaging the last mentioned member, mounted in the secand a stud extending from said plate into said spring.

3. In combination with a supporting spring and the body of a vehicle, plate associated with one of said members, a

an auxiliary Vtion to said lugs,

with said plate and abuttingA an anchor stud extending from said anchor plate,`anl auxiliary sprm into which said stud extends intepose intermediate the supporting spring and body, said plate having latorally elongated slots to accommodate connection to parte varying in size, and fastening means extending through said slots.

In combination wit a supporting spring and a body of a vehicle, an anchor plate associated with one of ugs integral with said plate and abutting the last'mentioned member, integral lu on said plate extending in the opposite irechook bolts engaging the last mentioned member, mounted in the second mentioned lugs, and a stud extending from said plate into said s ring, an anchor plate in engagement with t e spring, a stud rsingrfrom said plate and extending into the auxiliary spring, said anchor plate having elongated slots to facilitate attachment to parte var ing in size, and fastening means extending t irough said slots.

In testimony whereof I affix my signature inthe presence oftwo witnesses.
